STAPLING-MACHINE.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed December 16,1914. Serial No. 877,523.

a citizen of the United States, residing at Cincinnati, in the county ofHamilton, State of Ohio, have invented certain new and usefulImprovements in StaplingMachines, of which the following is adescription, reference being had to the accompanying drawing and to thefigures of reference marked thereon.

My invention relates to new and useful improvements in stapling machinesfor paper or fiber shipping cases.

The object of my invention is to provide a stapling machine of thischaracter in which an anvil is employed to pass under the cover of ashipping case and upon which the staples are clenched to more securelyfasten the case closed and at the same time to prevent injury to thecontents of the case.

Another object of my invention is to provide an automatic staple feedingmechanism for the machine, whereby the staples are automatically broughtinto position to be clenched on the anvil.

A still further object of my invention is to provide a simple, cheap andeffective machine of this character, in which the anvil is removablysupported so that it can be readily inserted in the shipping caseunderthe cover and yet provide a machine which is absolutelyself-contained.

In the accompanying drawings :Figure I 1 is a side elevation of myimproved stapling machine; Fig. 2 is a top plan view of Fig. 1, showingthe anvil, in dotted lines, swung around; Fig. 3 is a transversevertical sectional view taken on the line 3-3 of Fig. 4; Fig. 4: is alongitudinal sectional view taken on the line 44= of Fig. 2; Fig.

5 is an end view of the U-shaped spring used for holding the hammercarrying block and the staple carrying block together; Fig. 6 is an endview of two different forms of staples used; and Fig. 7 is a sectionalview of the two forms of anvils employed.

Referring now to the drawings, 1 represents the anvil, which, as shown,is provided on its lower face with strengthening grooves 3 and 4 for thepurpose of turning the staple, which will be hereinafter morefullvdescribed.

The forward end of the anvil 1 is probolt 5, upon which is mounted theside rails 6 and 7, which are formed of a single piece having an eye 8surrounding the bolt. In order to support the side rails 6 and 7 abovethe anvil, a series of washers 9 are placed upon the anvil surroundingthe bolt and the space 10 formed by these washers between the anvil 1and the side rails 6 and 7' allows for the cover of the shipping case,as will be later described.

In order to hold the side rails 6 and 7 in a position parallel with theanvil and firmly clamped thereto, the side rails are provided with abolt 11, upon each end of which, outside of the side rails 6 and 7, aremounted links 12- and 18. which are free to swing on the bolt 11.Pi'votally' mounted near the lower'end of the links 12 and 13 is a shaft14, carrying the cam 15, which is adapted to enter the recess 16 in thelower face of the anvil and clamp the side rails in their properposition in respect to the anvil.

Slidably mounted upon the side rails 6 and 7 are blocks 17 and 18connected together by a transverse bolt 19, upon which them to enter thetwo slots 24 and 25 in the bottom of the box or hopper 21 and traveldown through the run-way, as fully shown in Fig. 2 of the drawings. Thelower end of the run-way 20 is provided with a horizontally' arrangedportion 26 which causes the staple to assume a vertical position againstthe hammer 27. The staple 28, as shown in Fig. 6. is made of flat metalof a thickness slightly lessthan the slots 24 and 25, so as toeasily'slide down through the slots by gravity and travel down therun-way, but are of such a width that they can not twist therein andthus prevent them binding against the sides of the slots durprovidedwith a handle 32, by means-of which it is rocked upon the shaft 31. The

inner and lower end of the handle is pro staple rests While being forceddownwardly by the hammer 27. r

In order to hold the blocks 17 and 18, carrying the staple feedingmechanism and the blocks 29 and 30, carrying the hammer, in their spacedrelation, on the side rails .6 and 7, I employ a U-shaped spring 35,

which provides for the proper elasticity between the blocks to permitthe forcing through of the staple. The end of the anvil opposite thatcarrying the vertically disposed oolt, is sharpened in order that it maybe forced through the shipping case in the event that the shipping caseis not provided with the openings for this purpose.

The operation is as follows: The box 21 is filled, or partially filled,with staples and the cam 15 is swung downwardly, so as to release thetwo links 12 and:13 carried by the side rails 6 and 7, and then swungupwardly around the pointed end of the anvil. The anvil is then swung toone side, as shown in dotted lines in Fig. 2, and is forced through thesides of the shipping case, and preferably through the openings formedtherein; but if the shipping case is not provided with such openings,the pointed end of the anvil is forced through the material of the case.When this has been done, the top of the box rests upon the upper face ofthe anvil and the side rails are'then' swung around parallel with andabove the anvil, as shown in full lines in Fig. 2 of the drawings. Inthis position the outer pointed end of the anvil is beyond one side wallof the shipping case and the pivot carried thereby is on the outside ofthe other side wall of the shipping case.

The links 12 and 13 are swung down- ,wardly, bringing the cam 15 belowthe anvil and the side rails.

The hammer 27 1s moved upon the side rails, carrying with it, throughthe mediumof' the spring 35, the blocks 17 and 18 of the staple fillingmechanism to a position adjacent the vertical bolt, or adiacent thesidewall of the shipping case. By rocking t'he 'hammer 27 and turningthehandle 23., 'thegstaplesare caused to tr'avel downwardly through theslots 24 and 25 to the foot 26 and assume a vertical position againstthe hammer 27. By a slight rocking of the hammer27, through the handle32, the 'sta-- pie is caused to move horizontally against the block 34:and by swinging the handle forward in the direction of the arrowiin Fig.1, the groove 33, at the lower end of;

the hammer, engages the staple and forces it downwardly through the topof the box,

the prongs. of the" staple enteringthe grooves 3 and 4 in the anvil andbeing turned outwardly and firmly clenched.

In the drawings,'l have shown the anvil 1 having 'a strengthening rib 2on its lower face, but it will be understood that an anvil having aperfectly fiat lower face, such as 2 shown 111 Fig. 6 of the drawings,could be employed. In inserting the anvil, as heretofore described, itis inserted below the cover of the box but above the, contents thereofon which it rests during the stapling operation.

Having thus described my invention,

what I claim as new and desire to secure b Letters Patent, is:
